Devices Disrupt Restorative Sleep

A new study shows that reading from an electronic device in the evening causes pervasive sleep disruption.  Compared to reading from printed material, device reading suppressed melatonin secretion, delayed sleep onset, reduced REM (dream) sleep and impaired morning alertness. If you must use devices in the evening, try wearing blue-light blocking glasses that filter out the sleep disruptive wavelengths. Sweet dreams!
